How to Keep Your Summer Blonde From Going Brassy

Summer looks great on everyone. Your blonde? Not always.

One pool day can turn bright blonde yellow, green, or even a little orange. I’ve seen it walk through my door more times than I can count.

I’m Libby. I’ve been coloring hair for over 30 years. Here’s the truth most colorists know: summer damage isn’t a given. The right habits keep your color fresh, even with daily beach trips and endless pool hours.

Let me show you exactly how.

What Summer Does to Blonde Hair

Blonde hair takes more damage in three summer months than in the whole rest of the year. Here’s why.

When we lighten your hair, we change it. Lightened hair is more porous than virgin hair. Porous means thirsty. It soaks up everything it touches. That’s wonderful in my chair when I’m toning you. It’s awful at the pool.

Summer hits your blonde with a few things at once:

  • Sun. UV rays break down the color and turn cool blonde warm. Think yellow and orange. The sun weakens each strand, too.
  • Chlorine. It clings to bleached hair and reacts with copper in the water. That’s what makes the green tint. Yuck.
  • Salt water. It pulls moisture right out and lifts the cuticle. Your hair ends up rough, tangled, and dull.
  • Heat and humidity. They swell the strand and make it even more porous. So it grabs damage faster and loses color faster.

Once you know what you’re up against, you can fight back. The trick is simple. Build a wall before you get in the water. Don’t wait and try to fix it after. Fixing is always harder, and pricier, than protecting.

Soak Your Hair Before You Swim

Walking into a pool with dry blonde hair is like leaving your front door wide open. Don’t be shocked when something gets taken.

Your hair is a sponge. A dry sponge soaks up a lot. A wet sponge can’t hold much more. So if you soak your hair with clean water first, it can’t drink in as much chlorine or salt. This one habit saves more color than any fancy shampoo.

Here’s what I tell my clients to do every single time:

  1. Soak your hair with fresh water first. Use a shower, a hose, or a water bottle. Wet hair drinks 70–80% less pool water.
  2. Add a leave-in or oil. Coat it from mid-length to the ends while soaking wet. Coconut oil, argan oil, or any leave-in works. It acts like a raincoat.
  3. Pull it up. A bun or braid keeps less hair touching the water. Less contact, less damage. Bonus: fewer tangles.

Do this every time and you’ll see it by August. The folks who skip it are the ones in my chair begging for color correction. Don’t be that person.

How to Use Purple Shampoo the Right Way

Purple shampoo is not an everyday product. Use it wrong and your hair looks worse, not better.

Most blondes grab the purple bottle whenever they panic about brass. That doesn’t work. Timing matters more than the brand. The purple pigment cancels out yellow and orange. But too much turns your hair dull and grayish. Too little does nothing at all.

Here’s how to do it right:

  • Use it once or twice a week. No more.
  • Put it on wet hair. Let it sit 3–5 minutes, then rinse. (Check your bottle. Some are stronger.)
  • Focus on the brassiest spots. Usually that’s the top and the pieces around your face that catch the most sun.
  • Rinse with cool water to seal it in.

Is your hair very porous from lots of lightening? Start with two minutes and build up. Super-porous hair grabs pigment fast. You don’t want a patchy purple cast. Easy does it. You want a gentle fix, not a whole new color.

Give Your Hair Sunscreen Too

You’d never skip sunscreen on your face. But almost everyone forgets their hair.

Hair doesn’t burn like skin, so you can’t see the damage right away. By the time your blonde looks fried, the inside of the strand is already wrecked. UV protection for hair works just like it does for skin. It blocks the rays before they get in.

Three easy ways to shield your hair:

  1. Wear a hat. A wide brim, a ball cap, even a light scarf. Nothing beats it. This is the best UV defense there is.
  2. Use a leave-in with UV filters. Look for words like avobenzone or benzophenone on the label. Same blockers as sunscreen, made for hair.
  3. Spray on hair sunscreen. Reapply every couple of hours, just like face sunscreen. Most people spray once and forget. Then their hair is bare all day.

A hat will always beat a bottle. If you’re serious about your blonde, make friends with hats and cute updos. Less sun on your hair means less work in my chair.

What to Do the Minute You Get Out of the Water

The five minutes after swimming matter more than you think.

Chlorine and salt don’t quit when you climb out. They keep eating at your hair until you rinse them off. Letting your hair air-dry with pool water still in it? One of the worst things you can do. The damage gets stronger as it dries.

Do this instead, right away:

Rinse with fresh water. Use the pool showers. At the beach, bring a jug of clean water just for your hair. This alone washes away most of the bad stuff before it sinks in.

Add a conditioner or mask. Leave it three minutes. Focus on the ends. They’re the oldest and most fragile part of your hair.

Finish with cool water. Cool water closes the cuticle and locks the good stuff in. Hot water opens it back up and invites more trouble.

The clients who do this look like they were never in the water. The ones who skip it show up with straw. Five minutes saves you a fortune.

Hair Coloring Tips for Women Over 40 in Summer

I get asked for hair coloring tips for women over 40 all the time, especially this time of year. Here’s the honest truth. Your hair changes as you go. It can get drier and a little more fragile. So summer hits it harder.

A few things help:

  • Go a touch warmer with your blonde in summer. Warm tones hide brass better than icy ones do.
  • Stretch your color appointments with smart care at home. Less time in my chair, more time enjoying the sun.
  • Think about your gray, too. Some of my clients use summer to start transitioning to a gray hair style instead of fighting it. It’s a gorgeous, low-stress path, and I’ll walk you through every step.

Whatever stage you’re in, your color should fit your life. We talk it through first. Then we pick a plan you can actually keep up.

Mistakes That Wreck Your Summer Blonde

Even with good intentions, small slip-ups add up. Here are the ones I see most.

Washing too often. Every wash strips a little of the toner I put in. In summer, wash 2–3 times a week, tops. Use dry shampoo on the other days.

Over-using clarifying shampoo. Yes, you need to clear out chlorine and buildup. But clarifying shampoo strips everything, color included. Once a month is plenty.

Skipping deep conditioning. Summer blonde needs a real mask every week, not just regular conditioner. Look for one with protein and oils.

Forgetting about your hot tools. Your hair is already stressed from sun and water. Pile on a hot iron and you’re asking for breakage. Air-dry when you can. Always use heat protectant.

Thinking pricey means better. It doesn’t. A drugstore leave-in with UV filters works as well as a luxury one if the ingredients match. Read the label, not the price tag.

Good news: all of these are easy to fix. Most summer damage comes from small habits, not one big disaster. Clean up the routine and your hair bounces back in a few weeks.
